As PP flame retardant materials are more and more widely used in household appliances, electronics, automobiles and other industries, the demand for PP thermoforming flame retardant materials is increasing. However, cast PP blister materials are copolymers with a very large polyethylene content. The flame retardant effect on the material is poor

Abstract
The invention discloses a casting type flame-retardant blister coiled material which comprises the following components in parts by weight: 40 parts of polypropylene; 20 parts of high densitypolyethylene; 20 parts of low densitypolyethylene; 2 parts of brominated polystyrene; 3 parts of antimonous oxide; 0.3 part of an antioxidant 1010; and 5 parts of talcum powder. The invention discloses a preparation method of the casting type flame-retardant blister coiled material. The preparation method comprises the following steps: (1) stirring and mixing 40 parts of polypropylene, 20 parts of low-density polyethylene, 20 parts of high-density polyethylene, 2 parts of brominated polystyrene, 3 parts of antimonous oxide and 0.3 part of antioxidant 1010; (2) heating, extruding and blanking an obtained mixture at 180 DEG C by using an extruder; and (3) cooling and trimming an obtained extruded material to obtain a finished product. The casting type flame-retardant blister coiled material and thepreparation method thereof have the following beneficial effects that the flame-retardant effect of the PP blister coiled material can be improved, synergistic flame retardance is achieved in an organic and inorganic flame-retardant mode, and the purpose that a product achieves the V0-level flame-retardant effect under the condition that the blister effect is not affected is achieved.
Description
technical field [0001] The invention relates to a PP plastic-absorbing flame-retardant material required for home appliances, electronics, automobiles, etc. and a preparation method thereof, in particular to a cast-type flame-retardant plastic-absorbing coil and a preparation method thereof. Background technique [0002] In order to meet the needs of social safety production and life and prevent fires, the application of plastic flame retardant materials has gradually developed. PP flame retardant materials occupy an important position in plastic flame retardant materials due to their excellent performance. As PP flame retardant materials are more and more widely used in household appliances, electronics, automobiles and other industries, the demand for PP thermoforming flame retardant materials is increasing. However, cast PP blister materials are copolymers with a very large polyethylene content. The flame retardant effect on the material is poor. Contents of the inventi...
